[Class 56] A glass cutting machine comprises an intermittently moved conveyer and two sets of cutters. One set of cutters is carried by a support which is moved transversely across the glass whilst the conveyer is stationary, whereby transverse parallel cuts are made in the glass during the operative stroke of the support. During the return stroke of the support, during which time the transverse cutters are held out of contact with the glass by the arrangement described in Specification 606,452, the conveyer is moved forward beneath a set of stationary cutters. These cutters are gradually lowered into contact with the glass by an electromagnet and cam as described in Specification 606,479 and make longitudinal parallel cuts in the glass whilst the conveyer is in motion. The action is initiated by a manual switch to start the motor moving the transverse support for the first series of cutters, this motor being reversed automatically at the end of the operative stroke of the support and switched out automatically at the end of the reverse stroke of the support. A motor for driving the conveyer is automatically switched in at the end of the operative stroke of the carriage and is automatically switched out at the raising of the second set of cutters when they have completed the longitudinal cuts in the glass. Automatically operated means are provided for controlling the position of the sheet on the conveyer, both longitudinally and transversely. The electric means operating the tools may be replaced by equivalent pneumatic devices.
